Application filed September 8, 1919. Serial No. 322,467.

"To'all whom it may mm,

Be itknown'that Lemme Fox, a citizen of theUnited States, residing at Wichita,

' in' the county of Sedgwick and State of Kansas, have'invented' a new and useful Intake-Manifolch'of which the following is a specification.

' This invention relates to intake manifolds for automobiles, one of its objects being to provide a device adapted to be substituted for the manifold ordinarily employed and which can be utilized as a means for preheating the gas prior to the starting of the pecially in cold weather. v A further object is to provide means whereby heated air can be supplied in desired amounts, said airbeing heated by the.

- exhaust after the engine has been started.

A stillfurther object is to provide means for supplying moisture to the n'nxture thereby to render it more efficient.

Specification of Letters Patent.

"motor, thus to facilitate the starting, es-

A further object is to provide a device of V this character Wl'llCl'l can be substituted if readily for the ordinary manifold.

IVith the foregoing and other objects in view Wl11Cl1 will appear as the description proceeds, the invention consists of certain novel details of construction and combinations of parts which will be hereinafter more fully described and pointed out in the claims, it being understood that various changes may be made in the construction and arrangement of parts without departing vantages of the invention as set forth in the appended claims.

In the accompanying drawings the preferred form of the invention has been shown.

In said drawings A Figure 1 is a side'elevation of the device parts being broken away and the slidable burner beingshowmby dotted lines, in ex-' tended position. 7

Fig.2 is an end elevation. V

Fig. 8 is a transverse section through the slidable burner;

Fig. 4 is a detail View showing the latch of the slidable burner.

Referring to the figures by characters of reference, l'designates the stem of the intake manifold and 2 the arms thereof, there being the usual clamps shown generally at 3 and the exhaust manifold shown at 4. The

carbureter 5 opens into the stem, 1 as ordi- Patented July 27, 1920.

narily and is take.

Fitted around the stem 1 and the lower portions of the arms 2 of the intake is a casing 6 the top of which is connected to a hot air intake pipe 7 terminating in an elongated hood 8 which extends along and lies close to although spaced from the exhaust manifold so that when said manifold is heated it will also heat the thin sheet of air drawn into the hood 8 by the suction of provided with the usual gas in- "the engine.

A tubular extension 9 projects from the holder has tubes 18 extending upwardlyfrom the bottomthereof for supplying air and the wick 19 saturated with alcohol or i from the spirit or sacrificing any of the adother fuel is adapted to lie within the holder and around the tubes. Spaced notches 20 are formed in the side of the closure and either of them is adapted to receive a spring catch 21 so that the closure will thus be held in either of two positions.

Mounted within'the extension 9 is a butterfly valve 22 and an arm 23 extends from the stem of this valve and is connected by a rod 24 to one end of the closure 14. A cover 25 is hingedly connected to the casing 6 and is adapted to lie on the projecting portion of the closure 14 and shut it when positioned as shown by dotted lines in Fig.1.

In using the device herein described the wick is saturated with alcohol or the like, it

being understood that the closure is normally in the position indicated by dotted lines in Fig. 1 and that it is then possible to saturate the wick simply by raising the cover 25 and pouring the fuel onto the wick. When the closure is in this normal or extended position the valve 22 is open. In starting the engine the fuel is ignited and the closure 14 is then slid to position across the open lower end of the casing 6. During this movement of the closure the rod 24 will and the gas when sucked thereinto bythe pistons of the engine will be quickly vaporized and insure the starting of the motor.

Before the engine is started, the closure lt is pulled out to its normal or extended posi- .tion and the cover is lowered thereonto to extinguish the flame. This will bring the water receptacle 16 to position under the casing 6 and the vapor arising therefrom will mix with the air in the casing and flow therewith to the carburetor by way of the goosen'eck 10, the valve 22 being opened by the movement of the closure '14: to extended position.

Air is supplied to the casing 6 through the hoodS and pipe 7 and as it is taken from the hot surface of the exhaust manifold it will be in a highly heated condition after the engine has once started. The catch 21 will hold the closure ineither of the two positions to which it may be moved.

\Vhat is claimed is I The combination with the carbureter,

intake manifold and exhaust manifold of an engine, of a casing housing a portion of the intake manifold, means for supplying air thereto from the outer surface of the exhaust manifold, means for directing heated air from said casing to the carburetor, a burner movable into and out of position under-the casing, and means operated by the movement of said burner into and out of position under-the casing for closing and opening communication, respectively, between the casing and the carbureter.

2. The combination with the carbureter, intake manifold and exhaust manifold of an engine, of a casing housing a portion of the intake manifold, a means for supplying air to the carbureterfrom the casing, a valve controlling said means, a burner movable into and out of communication with the interior of the casing, and means operated by the movement of the burner to open and close the valve. v 3

3. The combination with a carbureter, intakemanifold and exhaust manifold of an engine, of a casing housing a .portion of the intake manifold, a valved connection between the casing and the carbureter, means for conductingheated air from the exterior surface of the exhaust manifold to the casing, a burner movable into and out of communication with the interior of the casing, and means operated by the movement of the burner for actuating the valve in the connection. 7

l. The combination with a carbu'reter, in-

take manifold and exhaust manifold of an engine, of a casing housing a portion of the intake manifold, means for conducting thereto heated air'from the surface of the exhaust manifold, means for conducting air from the casing to the carbureter, a valve, a combined water receptacle and burner constituting a closure for the bottom of the casing, the burner being movable into and out of position under the casing, and means operated by the movement of said receptacle and burner for opening and closing th valve.

5. The combination with a carbureter and intake manifold of an engine, of a casing housing a portion of the manifold, means for conducting air from the casing to the carburetor, a valve in said means, a closure movably connected to the bottom of the easing and including a water receptacle and a burner, saidclosure being movable to bring the burner into or out of communication with the interior of the casing, a cover for the burner when out of communication with the interior of the casing, and means operated by the said closure for opening the valve and for closing it. 7

6. The combination with the carbureter and intake manifold of an engine, of a casing housing portion of the manifold and having an air inlet, means for conducting air from the casing to the carbureter, a valve in said means, a closure for the'bottom of the casing and having a water container and a burner, said closure being movable to place the burner in or out of communication with the interior of the casing, means for fasten ing the closure in either of said positions, and means for transmitting motion to the valve from the closure. 7

In testimony that I claim the foregoing as my own, I have hereto a'lfixed my signature in the presence of two witnesses.
